8 I will bring them [back] to live in Jerusalem. They will be My people, and I will be their faithful and righteous God."
9 The Lord of Hosts says this: "Let your hands be strong, you who now hear these words that the prophets spoke when the foundations were laid for the rebuilding of the temple, the house of the Lord of Hosts.
10 For prior to those days neither man nor beast had wages. There was no safety from the enemy for anyone who came or went, for I turned everyone against his neighbor.
11 But now, I will not treat the remnant of this people as in the former days"-the declaration of the Lord of Hosts.
